I have a 2006 Civic with the stock headunit. I hooked up a Tsunami LOC to my rear speakers. I am setting the gain by hooking up the RCAs to the LOC and taking voltage readings from the other end of the RCAs. The voltage goes from 0 to .4xx volts. Four-tenths of a volt with the knobs maxed out. Isnt it supposed to go higher than that... like around 4 volts? I played a 70hz test tone at 30/40 volume (75%).
The RCAs are going to my amp to power a 400w RMS subwoofer.
Even though the pre-out voltage is less than a volt, the speaker-out on the amp is able to reach the correct voltage while setting the amp gain using DMM method. The subwoofer sounds fine too.
This LOC has been installed 3 years ago and I am re-installing it after going back to my stock headunit after removing my Alpine headunit. I dont recall the voltage not being able to reach 2 or 3 volts.
Why is it so low?
Thanks
